FAUCET.

Specification of Letters Patent.

Appliea tion filed May 13, 1916.

1 '0 all whom it may concern:

Be it known that I, HENRY D. :KELLY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

This invention relates to faucets, and has for its object to produce a faucet having a spring-seated valve so guided that it always fits its seat with a leak-proof joint and thus effectually guards against waste by leakage. More specifically the prime object of the invention is to produce a valve seat, and a valve, and separate means for seating and for unseating the valve without subjecting the same or the seat to frictional wear at any point where it tends to produce play between the parts which would result in lealn age.

Another object is to produce a faucet having means for automatically closing the valve, means for preventing the automatic closure of the valve, and means for cutting the valve out of service when desired.

With these general objects in view, the invention consists in certain novel and peculiar features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure '1, is a top view of a valve embodying my invention.

Fig. 2, is a view showing the same partly in elevation and partly in central vertical section.

Fig. 3, is a vertical section taken' on' the line III-III of Fig. 1.

In the said drawing, 1 indicates the body of the faucet and 2 the stem adapted to be screwed into an urn, not shown, for dispensing coffee, milk or other liquid, and controlling the passage of said stem is a plugvalve 8, having a diametric score across its head to indicate by its position whether the plug valve is open or closed, said plug valve standing open when the urn is in service.

Forward of the plug valve the passage of v the stem opens into a vertical cylindrical chamber 5, and at the lower end of said chamber is a circular head or flange 6 constituting a vertical guide and an upwardlyfacing valve seat. Below and of internal diameter slightly greater than the bore of the valve seat is a spout 7, the said spout Patented Got. 22, 1918.

being bifurcated at its forward side at 8 to register with the space between a pair of parallel ears 9, projecting forwardly from the body 1.

The upper end of the valve chamber 5 is threaded at 10 for engagement andclosure by a screw cap 11, which cap is provided with a central vertical socket 12, the socket being made of considerable length by forming the lower end of the cap with a reduced cylindrical extension 13.

The valve occupies the valve chamber 5 and normally rests upon the valve seat, and is provided with a cylindrical stem 15, extending upwardly and fitting slidingly and snugly'in the socket of the cap.

The valve is also provided with a depend ing guide and operating stem 16, having a bearing against the inner side of the head or flange 6, and the opposite sides of said stem 16 are cut away or flattened to produce water-ways between said stem and the wall of the spout.

The stem 16 is bifurcated at its lower end at 17, and said bifurcation registers with the bifurcation of the spout. An operating lever 18 fits snugly in the space between the ears 9 and is pivoted on pin 19, extending through said ears.

The lever 18 is provided at its lower end with a rearwardly projecting foot 20 which bears against the lower end of the valve stem 16 within the bifurcation thereof, the point of contact between the valve and the valve seat being in approximately the same horizontal plane as the pivotal point of the lever so that when the handle 21 of the latter' is pulled forward the said foot imparts direct upward movement to the valve to unseat the same without applying lateral pressure against it or its stem or the guides thereof, it being noted that the unseating of the valve is resisted by a helical spring 22 fitting around the stem and the depending extension 13 of the cap, and bearing at its opposite ends against the cap and valve with sufficient force to instantly reseat the valve and return the said lever to nornal position when preponderating power is removed from the handle. To prevent the valve being raised sufficiently to impose unnecessary strain on the spring 22, a stop pin 23 connects the ears 9 and extends through a short slot 24, in the lever.

Pivoted on the faucet and retained in position by the cap 11, is a ring 25 provided with an arm 26 to be disposed in the path of rearward movement of the lever when the valve is open, to prevent automatic closure thereof, and said arm is provided with an extension or thumb piece 27, upon which pressure can be applied to trip the arm from the path of the lever and thus permit the spring to reseat the valve, it being understood that when the spring reseats the valve it effects its engagement with the seat through impact without sliding or frictional contact.

To draw a cup of coffee from the urn, the handle is pulled forward. This unseats the valve and the coffee flows from chamber 5 below the valve and downwardly around the stem 16 thereof. T he stream is divided but not scattered, by the foot of the lever in passing the same but reunites and issues in a single stream from the spout. "When the cup is fully charged, the pull on the handle is relaxed, and the valve is instantly reseated and efi'ectively cuts off the flow through the faucet. The fact that the spout is vertical and very short prevents material drippage after the valve is closed.

Valves which become loose and permit of leakage are particularly objectionable in places where such valves have to be operated many times a day, as when used on coflee urns and the like-in fact the waste is so appreciable that the valves have to be reground at frequent intervals. The valve of this faucet eliminates waste and cost of regrinding as it seats by impact only and does not become loose through long service.

If it is desired to draw a bucket of coffee, the operator can be relieved of holding the handle with the valve opened by proper adjustment of the ring 25, and can cut off the flow by simply turning the ring until its arm 26 is withdrawn from the path of the lever; Should access to chamber 5 be desired, for cleansing or other purposes, without remov- Gopies of this patent may be obtained for five cents each. by addressing the ing the faucet from the urn the passage of the stem can be closed by proper adjustment of the plug valve, and the same can also be adjusted to regulate the volume of flow.

From the above description it will be apparent that I have produced a faucet for urns, possessing the features of advantage enumerated as desirable and I wish it to be understood that while I have illustrated and described the preferred embodiment ofxthe same I reserve the right to make all changes falling within the spirit and scope of the appended claim.

1 claim:

A faucet provided with a vertical cylindrical chamber, a spout connected with the lower end of said chamber and provided with a bifurcation in the front portion of its wall, and a circular flange forming a guide and an upwardly-facing valve seat at the lower end of said chamber, a cap closing the upper end of said chamber, provided with a socket alined with the axis of said valve seat, a valve upon said seat and provided with a stem slidingly engaging said socket and with a depending stem slidingly engaging the guide wall of said flange, a spring fitting around the first-named stem and hearing at its ends against the valve and cap to hold the former seated, a lever mounted on the faucet and provided with a foot extending through the bifurcation of the spout and engaging the depending valve stem to unseat the valve when the lever is pulled, means for engaging the lever to limit the valve-opening movement thereof, and a ring mounted on the casing of the valve for rotation in a horizontal plane, and provided with an arm for disposal in the path of closing movement of the lever to hold the valve open.

In testimony whereof I affix my signature.
